tricky find and replace
 

Ok I have 400 workbooks where I need to copy information into another cell.
I need it it to search worksheet "Data Entry" for "G. Cut Length" When it
finds that I need it to move down 16 rows. The data in that row needs to be
saved for the find. then I need to move down another 16 rows, the data in
that cell will be what needs to replace the find data. I wand it to search
for the find data on entire workbook and replace it with the other cell. "G.
Cut length is always in column C but the row changes, but the data to find is
alway 16 cells lower, and the to replace the find is always another 16.
Thanks for any help.
